
Home position: If it has Z phase, Z phase will be regarded as home position. Otherwise, home
position will be the encoder start up position.
Explanation 2
 It can also display negative values when setting analog input bias (Pr.03-03–03-10).
Example: Assume that AVI input voltage is 0 V, Pr.03-03 is 10.0% and Pr.03-07 is 4 (Bias serves as
the center).
Explanation 3
Example: If REV, MI1 and MI6 are ON, the following table shows the status of the terminals.
Normally opened contact (N.O.), 0: OFF, 1: ON
Terminal MI15 MI14 MI13 MI12 MI11 MI10 MI8 MI7 MI6 MI5 MI4 MI3 MI2 MI1 REV FWD
Status 0 0 0 0 0 0 0 0 1 0 0 0 0 1 1 0
NOTE: MI10–MI15 are the terminals for extension cards (Pr.02-26–02-31).
 The value is 0000 0000 1000 0110 in binary and 0086H in HEX. When Pr.00-04 is set to 16 or 19, the
u page on the keypad displays 0086H.
 The setting value 16 is ON / OFF status of digital input according to Pr.02-12 setting, and the setting
value 19 is the corresponding CPU pin ON / OFF status of the digital input.
 The FWD / REV action and MI1 (which is set to three-wire) are not affected by Pr.02-12.
 You can set 16 to monitor the digital input ON / OFF status, and then set 19 to check if the circuit is
normal.
Explanation 4
Assume that RY1: Pr.02-13 is set to 9 (Drive is ready). After the drive is powered on, if there is no
other abnormal status, the contact is ON. The display status is shown below.
Normally opened contact (N.O.)
Terminal MO20 MO19 MO18 MO17 MO16 MO15 MO14 MO13 MO12 MO11 MO10 MO2 MO1 Reserved RY2 RY1
Status 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1
 If Pr.00-04 is set to 17 or 20, it displays in hexadecimal “0001h” with LED u page is ON in the
keypad.
 The setting value 17 is ON / OFF status of digital output according to Pr.02-18 setting, and the
setting value 19 is the corresponding CPU pin ON / OFF status of the digital output.
 You can set 17 to monitor the digital output ON / OFF
status, and then set 20 to check if the circuit is
normal.
Explanation 5
Setting value 8: 100% means the motor rated torque.
Motor rated torque = (Motor rated power x 60 / 2π) / Motor rated speed
Explanation 6
Setting value 25: when displayed value reaches 100.00%, the drive shows “oL” as an overload
warning.
Explanation 7
Setting value 38
 bit0: The drive is running forward.
 bit1: The drive is running backward.
 bit2: The drive is ready.
 bit3: Errors occurred on the drive.
 bit4: The drive is running.

bit5: Warnings occurred on the drive.
